Clerical child sex abuse

With the scandal involving Cardinal Sean Brady, I think it is important for people to realise that there is no hope for placing any faith in the Catholic hierarchy to bring anyone to justice over the issue of child sexual exploitation by priests. Anyone who has access to Google and the internet can easily research the past popes’ roles themselves in covering up this matter. If the current Pope Benedict is guilty of this, which he is, then how do you expect the Vatican to take care of things?
